(1) Use the Canon Speedlites 420EZ and 300EZ
as fill-in flash in outdoor settings as well as for
normal flash when shooting at night or in a dim
ly-lit room. These units feature a built-in AF aux
iliary light function for dark situations, so you
can perform AF flash photography.
Speectlite 300EZ
FilMn flash:
This technique utilizes a flash unit as an
auxiliary light to prevent subject underex
posure in backlit situations. Generally, the
exposure level between the main subject il
luminated by the flash and the background
in ambient light must be balanced to avoid
unnatural
effects.
With
the
Canon
Speedlites 420EZ and 300EZ there Is no
need to balance this exposure level
because It is automatically controlled.
